Mrs. O on Letterman

The First Lady appeared on the Late Show with David Letterman last evening wearing a colorblock Preen Pre-Fall 2012 dress and Alexis Bittar marquis pin. Lovely!

P.S. For a fundraiser the same night, Mrs. O wore an inkwash silk printed panel dress from the Reed Krakoff Spring/Summer 2012 Collection, seen here.

The first lady spoke at the U.S. Department of Labor yesterday to support new rules proposed to help caregivers of wounded, ill and injured service members and veterans. The event was part of the ongoing Joining Forces initiative spearheaded by Mrs. Obama and Dr. Biden to support military service members and their families.

On the style front, Mrs. O wore a dress and jacket from the label Preen. The first lady debuted the ensemble during a trip to London last year, seen here.

Ahead of schedule, the President and First Lady travelled to London this evening to avoid travel complications from the Icelandic ash cloud. Arriving at Stansted Airport, Mrs. O deplaned in a stunning mix of colors and print, debuting a sleek electric blue skirt suit paired with a geometric print top and green kitten heels. Cathy Waterman earrings added a punch of orange color to complete the look. Love!

Update: Per Red Carpet Fashion Awards, Mrs. O wears an ensemble by Preen from the label's Fall 2011 collection, which was inspired by the Northern California Arts and Crafts movement. The choice is noteworthy, as Preen is a London-based label designed by Justin Thornton and Thea Bregazzi. To my knowledge, this is the first time that the First Lady has worn Preen for a public event. Perhaps it's a sign that Mrs. O will be making a sartorial nod or two over the coming days?
